1. Open the packaging.
2. The unit must be permanently mounted to a firm, level floor capa-
ble of supporting it. Ensure that the unit is positioned securely and
on a stable foundation. Any risk of movement should be removed
by suitable means, especially to avoid strain on any rigid dis-
charge piping.
3. When mounting the unit, install bolts through the mounting feet
and into the mounting surface. Do not bolt uneven feet tightly to
the foundation, as this will cause excessive stress on the receiver
tank. Use metal shims to level the unit if necessary.

5.5 Connection to Compressed Air Feed and Nitrogen Consumer

• Make sure that the inlet and outlet tubes are free of dust, particles, metal parts and curls, liquids and grease before
you connect the Nitrogen tire filling system.
1. Connect the receiver outlet to the plumbing or equipment.
2. Connect the compressed air supply to the compressed air inlet.
1. Make sure that the connections are correct.
2. Open the compressed air supply to 15psi.
3. Make sure that the installation has no leaks, which may have arisen due to transport.
4. Increase the air pressure to minimum feed pressure (Table 4.1). Check for leaks in plumbing.
5. Make sure that the system starts to consume pressurized air when the nitrogen outlet is opened and that air consumption stops when the
nitrogen receiver tank pressure reaches the high pressure setting.
6. Purge the receiver tank to remove ambient air. Allow to bleed for 15 minutes to ensure tank nitrogen purity is up to 95%.
7. The system is ready for use now.
The purity is factory pre-set at 95%. This means that there is 5% residual oxygen. The purity has been set by adjusting the flow
control valve. Normally the setting is stable and does not need to be checked.
Should you, however, want to adjust the purity, this can be done by adjusting the flow control valve till the purity, as measured
with an oxygen analyzer taking a sample from the outlet, has the desired purity.
The automatic pressure switch is factory pre-set such that the Nitrogen tire filling system switches off when there is no
consumption and that it switches back on when there is consumption of nitrogen.
The Nitrogen tire filling system is set at the factory at a pressure to stop the flow of air to the nitrogen generator upon reaching
the designated receiver pressure (Table 4.1). The system will automatically turn on upon a 15psi drop in N2 pressure in the
receiver.
Should your specific application require different settings it is possible to adjust this automatic pressure switch.
